HINGE.

Specification of Letters Patent. Patented Dec, 14 1920.

Application filed April 16, 1917. Serial No. 162,327.

To all whom it may concern:

Be it known that I, GEORGE W. NELSON, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinges and has special reference to that class of hinges adapted for connecting a sewing or other machine to its supporting table in a manner whereby the machine may be tilted in a direction to expose the mechanism on its under side for adjustment, repairs, or other desired purpose.

One of the objects of the invention is to provide an improved hinge connection of the type referred to that will be substantially concealed from view so as not to deface or disfigure the upper or exposed surfaces of the supporting table. v

Another object of the invention is to provide a hinge of the type in question that will be of simple and inexpensive construction and capable of ready and convenient attachment to its connectingparts, i. e. the machine and its supporting table.

These objects are attained by the novel construction, arrangement and combination of parts as illustrated in the accompanying drawings, in which,,

Figure 1 is a top plan view of a portion of a sewing machine and sewing machine table connected by a pair of my improved hinges, the table being broken away adjacent one of the hinges to more clearly show the. hinge and the manner of connecting it with the table.

Fig. 2 is an enlarged detail, in side elevation and section, showing one of the hinges and its connection with the sewing machine and sewing machine table.

Fig. 3 is a bottom plan of the hinge detached from connection with the sewing machine and sewing machine table.

Fig. 4 is a sectional elevation of the same. Elie section being taken on the line 4 4 of Fig. 5 is a bottom plan of the stationary member of the hinge with the movable member or tongue disconnected therefrom, and

Fig. 6 is an end view of the same, looking from the right in Fig. 5.

Similar reference characters indicate like parts in the several figures of the drawings.

Only so much of a table and a machine are here shown as is necessary to illustrate the application and use of my improved hinge, the portion of table shown being indicated at 2 and the machine at 3.

The table 3, like the tables or platforms of all sewing machine stands or cabinets, is provided with an opening 4 to receive the machine, or rather the mechanism at the under side of the bed-plate of the machine, the bed-plate itself being usually formed at its ends to overlie and rest upon the table. as shown in Fig. 1. For connecting the machine with its supporting table in a manner to permit of its being tilted upward to expose the mechanism at its under side, a pair of hinges are usually employed, as indicated in Fig. 1, which connect with the machine at its rear edge. As both hinges are similarly constructed, mounted and operated, a detailed description of one only will here be made.

The hinge comprises two main members pivotally connected together, one of which, indicated at 5, is adapted to be attached to the table in a stationary position, and the other of which, indicated at 6, is adapted to be attached to the machine.

The stationary hinge member 5 is of hollow cylindrical form and at its front end is slotted, as at 7, to receive the movable hinge member or tongue 6, which is connected thereto by the transverse hinge or pivot pin 8 supported by the opposite side walls of the member 5 as shown. At its rear end and in the lower wall thereof, the member 5 is longitudinally split, as at 9, in line with the open end slot 7, in order to permit of the same being expanded into locking engagement with the wall of the bore in the table in which it is adapted to be seated.

For attaching the hinge to the table, the latter is formed with a horizontal bore 10 at the edge of the machine opening 4, in which the hinge member 5 is adapted to be firmly held by means of a locking device, here shown in the form of a screw 11, which is screwed into the table from the under side thereof with its pointed end entered between the adjacent edges of the longitudinal split 9 and expanding the member 5 into clamping engagement with the wall of the bore 10. This clamping of the hinge member 5 in the bore 10 will ordinarily be sufiicient, but as a further fastening means and one that will positively lock the member against longitudinal displacement in its containing bore, said member is formed with an enlarged opening 12 at the adjacent edges of the split 9 in which the end of the screw 11v is received when forced into expanding engagement with the member.

The movable hlnge member 6 may be constructed in any suitable manner; for connectlon with the machine. As here shown itis formed as a narrow tongue which is 7 connection with and disconnection from the machine and its supporting table. Also, by reason of the stationary member 5 being seated in the horizontal bore at the edge of the machineopening 4, it is almost wholly concealed-from View andin this way avoids v defacing the exposed surface of the table, the only exposedpart of the hinge being the narrow upper edge of the pivotedtongue 6.

What I claim is 1. Ahinge comprisin an expansiblemember adaptedto be seated'in a bore, a cooperating' member pivoted thereto, and means forexpandin-gsaid expansible member and clamping-the same within-a contamingybore.

2. A hinge comprising a longitudinally split cylindrical member having a slotted front end,a cooperating member pivoted in the slotted front end ofsaid cylindrical member, and means for expanding the split cylindrical member and clamping the same within a containing bore.

3. A hinge comprising a longitudinally split cylindrical member having a slotted front endand an enlarged opening at the adjacent edges of its split portion, a cooperating member pivoted in the slotted front end of said cylindrical member, and a screw engaging the cylindrical member within said enlarged opening to expandsaid member and lock the same against movement within a containing bore.

4:. A hinge comprising atransversely expansible cylindrical member, means for expanding and clamping the member in operative position, and a second member pivoted to the end of the first mentioned member.

5. A hinge comprising a transversely expansible cylindrical member, a flat member pivoted at one end thereof, means for expanding-and clamping the cylindrical member in operative position, and means for locking the cooperating flat member in its en aging support.

igned at Cleveland, in the county of Cuyahoga, and State of Ohio, this 9th day of April, A. D. 1917.
